Estudio geotécnico in Sant Julià de Ramis

In Sant Julià de Ramis, formations of sandstone, conglomerates and flysch predominate, followed by compact gravels and sands, which provides good bearing capacity and often allows stable shallow foundations, especially in the denser strata. The occasional presence of white or soft expansive clays and fine soils such as sands and silts should be taken into account in localised areas, as it may be necessary to carry out targeted checks on compactness and the groundwater table. In sectors where outcrops of limestones, dolomites or marbles occur, the ground typically offers greater stiffness, although homogeneity may be affected by lithological transitions.

Seismic activity in the municipality is very low, with only a single recorded event in the last 30 years and a maximum magnitude of 1.7, which minimises the influence of seismicity on structural design. Nevertheless, due to the presence of carbonate materials, it is essential to investigate the possible occurrence of karst features before defining the foundation, given their potential to cause subsidence or localised collapses. The absence of a predominantly clayey substrate rules out significant risks of expansivity, with the main constraint being the detailed verification of karst-related phenomena in ground with limestones and dolomites.
